BATTERY MAINTENANCE GUIDE
SAFETY:
DANGER
Explosive hydrogen gas forms when batteries are
charging. An open fl ame or spark can cause this gas
to explode. Serious personal injury or property damage
could occur. Only charge the Batteries in this machine
in a well ventilated area.
WARNING
The Batteries in this machine produce hazardous
voltage which can cause electrical shock, burns and/
or electrocution. Always disconnect Batteries before
servicing this machine.
WARNING
Before you service a Battery, always wear face protec-
tion, protective gloves and protective clothing. Battery
acid or battery explosion can cause serious injuries.
WARNING
The Batteries in this machine contain sulfuric acid,
which causes burns to skin. If battery acid contacts
clothing or skin, rinse the effected area with cold water
immediately. If battery acid gets on your face or in your
eyes, fl ush the area immediately with cold water and
seek medical attention.
WARNING
Dress safely. Do not wear rings or metal wrist watches
when servicing this machine, as they can cause an
electrical short circuit which can cause serious burns.
INSPECTION AND CLEANING:
• Keep Batteries clean and dry from residue
• Check that all vent caps are tight
• Use a solution of baking soda and water to clean if
acid residue on Batteries or corrosion on the terminals
• Protective spray of petroleum jelly should be applied to
terminals to reduce corrosion
STORAGE:
• Batteries should be fully charged prior to and during
storage
• Never store discharged Batteries
• Store batteries in a cool, dry place but never below
freezing - Recharge in storage a minimum of every 30
days
• Recharge Batteries before putting them back into
service
WATERING:
• Add water, NEVER ACID, to cells (distilled water
recommended)
• Do not over water
• Before charging the Batteries, only add water if the
plates are exposed. Add just enough water to cover
the plates, then charge the Batteries. Once fully

MAINTENANCE
DAILY MAINTENANCE:
1. Remove the clean Pads / Brushes. Never use soiled
Pads / Brushes when cleaning. Replace Pads /
Brushes when they become packed with residue.
2. Remove and clean debris from the fl oat shut-off screen
and Drain Saver located inside the Recovery Tank.
3. Drain and rinse Tanks thoroughly and fl ush out solution
feed to Scrubdeck.
4. Inspect Vacuum Hose for any objects obstructing the
air fl ow.
5. Raise Squeegee and wipe Blades with a clean cloth.
Store Squeegee in the raise position to prevent
damage or setting of the Blades.
6. Wipe down machine if needed. Use a non-abrasive,
non-solvent cleaner or a clean damp cloth.
7. Recharge the Batteries if needed.
WEEKLY MAINTENANCE:
1. Check Battery water level in each cell of the Batteries
and fi ll as needed. Always use distilled water to refi ll
Batteries. Batteries should be fi lled approximately
3/4'' to 1'' above the plates. Overfi lling will cause
the Batteries to leak during charging. The charging
process creates gas bubbles inside the Battery, which
effectively increases the volume of the electrolyte.
2. Clean Battery tops to prevent corrosion.
3. Flip EDGE pads.
4. Drain and rinse tanks thoroughly. To thoroughly fl ush
out any solution chemicals in solution line valves, refi ll
Solution Tank with a few gallons of warm, clean water
and run the machine until Tank is empty.
MONTHLY MAINTENANCE:
1. Check Scrubhead and Squeegee lifting cables for
wear and spring tension.
2. Check machine for water leaks and loose nuts and
bolts.
3. Check to see if Battery cables are tightened. Tighten,
if needed, 8-10 ft/lb MAX.
4. Grease caster swivel and Squeegee pivot point.
YEARLY MAINTENANCE:
Call your local dealer for yearly maintenance.
STORING MACHINE:
1. Be sure to fl ush the tanks out completely. To
thoroughly fl ush out any solution chemicals in solution
line and valves, refi ll Solution Tank with a few gallons
of warm clean water and run machine until Tank is
empty.
2. Open the Recovery Tank lid to promote air circulation.
3. Raise Scrubdeck and Squeegee.
CHECKING BATTERY SPECIFIC GRAVITY:
Use a hydrometer to check the Battery specifi c gravity.
Checking Gravity:
• Hydrometer
• Battery
NOTICE
Do not take readings immediately after adding distilled
water. If water and acid are not thoroughly mixed, the
reading may not be accurate.
Check the hydrometer against this chart

NOTICE
If the readings are taken when the battery electrolyte
is any temperature other than 80°F(27°C), the reading
must be temperature corrected. To fi nd the corrected
specifi c gravity reading when the temperature of the
battery electrolyte is other than 80°F(27°C): add (+) to
the specifi c gravity reading 0.004 (4 points), for each
10°F(6°C) above 80°F(27°C). Subtract (-) from the
specifi c reading 0.004 (4 points), for each 10°F(6°C)
below 80°F(27°C).
